Quick Answer: What servers is the 253940R-001 compatible with?
The 253940R-001 is a HP laptop memory module. Confirm DIMM rank, voltage, and speed against the target server's supported memory list before deployment - mixed configurations may downclock to the slowest installed module. For server-specific population diagrams, email sales@prodisknetwork.com with your server serial number.
How fast does the 253940R-001 ship?
253940R-001 orders ship in 1–3 business days from US warehouses. Delivery is next business day to most metro ZIPs via FedEx/UPS overnight; ground delivery covers remaining US in 1-4 business days.
The 253940R-001 is deployed by US enterprises, MSPs, government, and education customers across multiple infrastructure scenarios. Below are the most common deployment patterns Pro Disk Network sees in real-world orders.
In-Memory Database — SAP HANA, Redis Enterprise, Apache Ignite, Aerospike — workloads that scale linearly with DRAM capacity.
Hyper-V Cluster Node — Windows Server 2019/2022 Hyper-V hosts with Storage Spaces Direct. Dynamic memory allocation makes higher-density DIMMs cost-effective.
AI / ML Training — PyTorch and TensorFlow workloads benefit from large host memory pools for dataset preprocessing and CPU-side feature engineering.
Tanzu / Kubernetes Workers — Worker node memory expansion for high-density container deployments. Plan for 8–16 GB per moderate Pod baseline.
What is the 253940R-001?
The 253940R-001 is a HP server memory module with capacity 64 MB and number of sticks 1, manufactured by HP. Pro Disk Network ships this part new and certified-refurbished from our US warehouse with dispatch in 1–3 business days, backed by a 30-day return guarantee.
Pros & Cons of 253940R-001
Pros
Lower cost than buying through the OEM channel
US shipping in 1–3 business days cuts deployment lead time
Cons
Memory must match existing DIMM rank/density for channel balance
Higher density modules can drop overall channel speed
BIOS update may be required on older revisions
Frequently Asked Questions about 253940R-001
Is the 253940R-001 a genuine HP part?
Yes. Pro Disk Network sources every 253940R-001 as factory-original HP inventory. New units arrive sealed in OEM packaging; refurbished units are pulled from decommissioned HP servers, surface-tested, and re-warranted by Pro Disk Network for 90 days.
What servers is the 253940R-001 compatible with?
The 253940R-001 is a HP laptop memory module. Confirm DIMM rank, voltage, and speed against the target server's supported memory list before deployment - mixed configurations may downclock to the slowest installed module. For server-specific population diagrams, email sales@prodisknetwork.com with your server serial number.

Compatibility: Rank, Density, and Channel Population Rules
Quad-rank modules behave differently from dual-rank: most modern Xeon platforms support 1-2 DPC (DIMMs per channel) at full speed with single- and dual-rank modules but downclock with quad-rank above 1 DPC. RDIMM and LRDIMM are not interchangeable in the same channel. ECC and non-ECC cannot be mixed. Server motherboards expect server DIMMs — the 253940R-001 is a server module and will not work in consumer desktop boards.
Pricing Strategy: New, Bulk, or Refurbished
If you are buying 16 or more modules at once, request a matched-lot quote: sequential manufacturing dates and serial numbers, which reduces variance in observed memory speeds across the channel. Pro Disk Network ships matched-lot orders for free on volumes of 16+.
